ARRANGEMENT OF MEANS FOR MAKING TIGHT JOINTS AROUND THE FAUCETS 0FWATER-COOLERS.

Specication of Letters Patent No. 21,819, dated October 19, 1858.

To all whom it may concern:

Be it known that I, JOHN S. CLARK, of the city and county ofPhiladelphia, in the State of Pennsylvania, have invented certainImprovements in Tater-Coolers; and I do hereby declare that thefollowing is a full and eXact description of the same, reference beinghad to the accompanying drawing and to the letters and marks thereon.

My invention relates to the making of a convenient and perfectly tightjoint between the faucet or cock and the passage which leads to theinterior of the well.

In general I construct my cooler similar' to ordinary coolers wherethere is atmospheric air or some non-conducting material between thewell and the shell of the cooler.

As represented by the drawing, which is a vertical transverse section ofa cooler taken on a central line through the well, shell and faucet, (a)marks the shell of the cooler; (Z9) the bottom and (c) the top or cover;(CZ) the shell of the well, the enamelng thereof being indicated inblue.

(e) marks the passage from the well to the shell, being the outlet ofthe well; (f) the faucet; (g) an extension of the outlet beyond theshell; (7L) a ring projecting outward from the shell, 'and the cap,which surrounds the faucet and covers the ring (7L) and projection (g).

It will readily be perceived that, by projecting the passage tube (g)beyond the shell of the cooler, and before the cap shall be permanentlyattached to the faucet, opportunity is afforded to make a good joint ysoldering the projection to the faucet and then the cap may be solderedto the shell and to the faucet and thus a tight and perfect oint be madeby soldering. It will, also, be perceived that an excellent joint canalso be made by first soldering the cap to the faucet and then fillingin the space between the edge of the cap and the faucet with cement andcrowding the faucet into the passage to the well, the cement adheringfirmly to the surfaces, between the projection ring (7L) and interior ofthe cap and exterior of the faucet. The means for forming this jointthen allows of either soldering or cementing being adopted and themaking of a firm and perfect joint either way. Cements of any known kindcan be used whether resinous or earthy.

In enameling the usual method is adopted by me for the well, and anydurable enamel which will resist the action of the more common waters isall that will he needed; but where it is designed to use the cooler formineral waters or for waters impregnated with alkalis or acids or anyingredient being held in solution which would act upon common enamels,the proper resisting enamel should be selected.

Having thus fully set out my invention what I claim as new and desire tosecure by Letters Patent is- The projection (g) ring (71.) and cap as anarrangement of means for allowing of the making of a perfect joint, asherein described.
